WOW AWESOME!!! So excited that you guys will be streaming the new Sailor Moon! I live in Canada so I was worried perhaps I wouldn't be able to get it through NicoNico...

So many questions though now...
1 Will it be only available to Premium members?
2 Will it be available to watch after the first live stream? If so, who will be able to view it?
3 Are you guys taking measures to beef up capacity for the livestream time? I'm sure there's going to be massive traffic...

From the announcement:

More details will be announced later, so keep your eyes here to Crunchyroll!

It seems unlikely that this would be just for premium members, at least for all but some select countries. The last simulcast I can think of that was premium members only for all countries was the original Fairy Tail series, and that was fall 2009. I can't think of one since that was premium only for Canada.

I've been here well before CR went legit, and I've never know CR to do anything that was "watch at a specific time or you won't be able to see it". Keep in mind the announcement says, "...streaming Sailor Moon Crystal this summer starting on July 5, at 3:00am Pacific Time!". That's the same language they use for any simulcast announcement. It simply means that is the earliest you can see it, not the only time. There was no mention of the word "live stream" in the announcement.

Given that the first availability of the stream will be at 3:00 AM Pacific, 6:00 AM Eastern on a Saturday morning, I think that would deter a lot of people from jumping on the stream as soon as it happens. Those who do view at that time (at least in this hemisphere) also should have few problems with internet congestion since most people will be snoozing away at that time.

Sailor Moon at 6 Am, It will seem like old times. Back in its run on WPIX in NYC in the 90's the only way I could get my then preschooler to wake up on time was to whisper, "Sailor Moon." in his ear. He was up like a shot. That's how my love affair with these girls began.

Sailor Moon!!! I MISS YOU! I miss Sailor Uranus and Neptune even more. I'm sure they won't be shown for a couple of years. All and all, I CAN'T WAIT!!

You may be surprised. Keep in mind the original series was more filler than source-based material.

As a comparison, Inuyasha: The Final Act covered 20 volumes of the manga in 26 episodes. The first edition of the Sailor Moon manga was only 18 volumes (reduced to 12 for the second edition, released around the time of the live action series, but no doubt the same number of chapters):http://en.wikipedia.org/wiki/List_of_Sailor_Moon_chapters

Sailor Uranus and Neptune won't be in this one since this is the first ark. If Sailor Moon Crystal does really good they will probably do the other arks.

Where have you seen anything to confirm this is only the first arc?

This isn't a remake of the original series, it is a new series based on the manga, which won't take nearly as many episodes. The original manga took only 33 chapters before it hit the Sailor Moon S arc, and the entire manga series from beginning to end was only 52 chapters.

I expect when this airs, we are going to see a lot of "Hey, they skipped...." complaints from people that don't know how much of the original series was filler.
